Cold Storage

Cold storage of color materials has been around for a few decades. The leading authorities on cold storage of color photographic materials are Henry Wilhelm and Carol Brower. They found that cold storage discourages the fading and deterioration of color photographs.

Supplies needed for cold storage include:

  • Freezer (frost free)
  • Ziploc airtight polypropylene storage bags
  • Disposable examination gloves
  • Metal storage boxes

A lot of people like to store photographs at home. Instructions for cold storage can be found in my Preserving Your Family Photographs book.

Don’t want to do this at home? You can rent space from a commercial cold storage facility called Hollywood Vaults (800) 569-5336.

Color Photographs: Deterioration

Color pictures are composed of two elements: the negative and the image. The negative is the film while the image is printed on different types of paper. Today, most photographs are printed on resin coated (RC) papers. This means that the image is printed on a paper coated with a substance that protects the print surface from abrasion. Over time, these RC papers develop cracking.

Kodacolor film, Ektachrome slides and Agfacolor color are three of the color photographic processes used by family photographers that have had disturbing preservation records.  However, instant pictures deteriorate the fastest.

Next week I’ll talk about instant pictures and special concerns.  You can read more about this topic in my book Preserving Your Family Photographs or contact me via email at
